Abstract
A valve housing receives a spool 34 and the spool has a regulating chamber 52 selectively communicating a supply line to a return line. The spool 34 is biased in one direction by a spring force and there is a second force biasing the spool in an opposed direction whith the second bias force being provided by a fluid pressure within a hydraulic system associated which the pressure regulating valve. The amount of communication between the supply port 111 and the return port 99 is regulated by a position of the spool 34 as the bias force from the fluid pressure change. Damper chambers are provided on opposed sides of the spool and serve to dampen a speed of movement of the spool and a supply line for supplying fluid into the damper chambers through check valves 44, 64. The supply line serves to assist in purging air outwardly of the damper chambers.
